'I'his invention relates to reels, and with regard to certain more specific features, to reels for hose and the like.

Among the several objects of the invention may be noted the provision of a hose reel particularly ing system rendering it more easy and certain of operation; the provision,in a reel of the class described, of means for manually turning the reel at a high mechanical advantage; the provision in a reel of the class described, of means for holding the reel against such displacements such ask would be occasioned if the vehicle on which the reel is mounted should encounter a sudden bump; and the provision of a reel of the class describedwherein permanent connection of the inner end of the hose is maintained through winding and unwinding operations. Other objects will be in part obvious and in part pointed out hereinafter.

'I'he invention accordingly comprises theelements and combinations of elements, features of construction, and arrangementsof -parts which will be exemplified in the structures hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawing, in which is illustrated one of various possible embodiments of the invention, y l

Fig. 1 is a side elevation of a reel embodying the present invention;

Fig. 2 is an ideal section taken substantially along line 2--2 of Fig. 1 certain parts being broken away for clarity; and,

Fig. 3 is an end elevation of a portion of the reel of Fig. 1.

. Similar reference characters indicate corresponding parts throughout the several views of the drawing.

Referring now more particularly to Figs. 1 and 2, numerals I indicate a pair of angle-iron pieces which, arrangedv parallel to each other, form' the base or support for the present invention.

At the opposite ends of the pieces I, there are bolted bracket pieces 2, which serve to space they 'gear teeth for the driving mechanism for the reel.

means of the slots 6, lateral'adjustments between the angle-iron pieces I may be effected for different width reels.

At the upper, outer extremities of eachA of the pieces 3 and 4, there is provided a bearing block 5 1. The two bearings 'I on each of the brackets 2 carry'a shaft 8, at the ends of which are mounted rollers 9. The particular construction of the rollers 9 is apparent in Fig. 2, wherein it is seen 5 that they comprise outer flanges I0 and a rela- 10 tively narrow inner groove I I. l

From the arrangement described, itwill be seen that there are two rollers 9 at each end of the base, and that, considered from the side, there are two lateral pairs of rollers in the same plane.

The rollers 9 constitute the supporting means for the reel proper, indicated by numeral I2. The reel proper comprises a .pair of circular side plates I3 and I4 respectively, secured parallel to each other, and coaxially, by a drum I5 centrally mounted therebetween. The drum I5 is cylindrical and is attached to the side plates I3 and I4 by inwardly extending flanges I6 and bolts I'I.

The diameter of the drum I5, which constitutes the surface upon which the hose is'reeled, is of course considerably less than the diameter oi' the side plates I3 and I4.

The drum I5 may comprise' a single sheet or plate of steel or the like, bent to cylindrical form and welded as indicated at numeral I8 in Fig. 1. Carried on the outer base of the side plate I4 is a circular ring gear or rack i9. The rack I9 comprises a flat steel annulus 20 and evenlyspaced cylindrical pins 2| .spacing said annulus 20 from said plate I4. The pins 2l are desirably press-fitted or Welded to both the plate I4 and to the annulus 20. The even spacing of the pins 2| permits them to be used as the equivalent of 40 Bolted to the outside of the left-hand angleiron piece I is a bracket 22, which has approximately a U-shape and is preferably made of welded angle-iron. A flat portion 23 at the top of the bracket 22 has bolted thereto a bearing block 24, in which is borne a shaft 25. The inner end of the shaft 25 carries a pinion 26, the teeth of which are of suitable shape and size to engage with the pins 2| of the ring gear I9 heretofore described. On the outer end of the shaft 25 there is removably secured a crank handle 21. By turning the crank 21 it will be seen that the reel as a whole is driven to rotate on the rollers 9. Because the point of engagement of the pinion 26 With the ring gear I9 is spaced at a considerable distance from the center oi rotation of the reel, and because of the relative diameters of said pinion 28 and the ring gear I9, it will be seen that a considerable mechanical advantage is obtainedl in driving the reel to rotate. This of course is of benefit in reeling up the hose or the like onto the reel.

In the center of the side plate I4 is provided a circular opening 28. The opening 28 is for the purpose of inserting the connecting mechanism to which the inner end of the hose on the heel is connected. The structure of this mechanism will be 'seen more particularly in Fig. 2. It comprises a dead-end flange 29 which is `bolted to the center of side plate I3, on the inside thereof. Screwed into the flange 29 is a short length of pipe 30, and to the opposite end of the pipe length 30, is screwed a Y-coupling 3I, the side outlet portion of which is at an angle of 45 degrees to the run of the fitting. A short nipple 32 connects the side outlet of the tting 3l to a L5-degree L 33, in the other end of which is in turn screwed a nipple 34. A hole 35 is provided in the drum I5 in the region of the nipple 34, and through this hole, there is screwed on the nipple 34 a 90- degree L 36. To the L 36 there is attached, by means of a suitable coupler 31, the inner end of the hose 38 which it is desired to reel on the device. A hand hole (see Fig. 1) is desirably provided in the side plate I4 in order to permit the insertion of a wrench or the like to tighten the connection of the hose to the L 36.

Returning to the Y-fltting 3I, the other side of the run of the :fitting receives the cylindrical end 39 of a swivel union 40. 'I'he end 39 is supported in a block 4I which is in ,turn carried on the upper or inner end of a plate 42 of sector shape. The plate 42 is supported on the side plate I4 by means of certain of the bolts I1, indicated by numerals 43, which have long collars 44 spacing said sector plate 42 inwardly from the side plate I4. The swivel union 40 has an elbow extension 45 on its other side, which is connected by a coupling 46 to a pipe 41. 'I'he pipe 41 communicates with the source of fluid in consideration. For example, if the reel is mounted on a tank truck, the pipe 41 connects to the tank.

It will be seen that the entire assembly comprising the elements 29, 30, 3l, 32, 33, 34, 35, 36, 39 and 40, rotates together with the reel as the same is turned by means of the crank 21. The swivel union '40, however, permits the assembly 45-'46-41 to remain stationary while the reel is being turned. This is of considerable advantage as it means that at no time during the use of the hose 38 need it be unfastened from the reel. In other Words, when a delivery is to be made,

all the operator needs to do is to unreel the hosefrom the drum, and immediately commence pumping liquid through it. In prior devices of this general type, it was ordinarily necessary to unreel the entire hose, connect the near end to the tank, and then commence pumping. When` the hose is to be re-reeled, as after a delivery has been made, again no connection nor disconnection need ne effected, but by merely turning the crank 41, the entire hose is reeled on the drum, and remains in position for the next delivery.

Encircling the upper half of the peripheries of the side plates I3 and I4 is a strap 48 which has a U-shaped cross-section as shown in Figure 2. The left-hand ends of the strap 48 are flattened as indicated at numeral and have slots 50 provided therein. Through the slots 5I pass studs or bolts 5I threaded into the analeiron pieces I. By loosening the studs II, the

tension in the strap 48 can be adjusted, as will be seen. 'Ihe other ends 52 of the strap 48 are likewise flattened. However, instead of being attached directly to the angle-iron pieces I, the ends 52 are attached to the oiset portion 53 (see Fig. 3) of 4a shaft 54 which is carried in upwardly extending standards 55 bolted to the opposite ends of the angle-iron pieces I. The left-hand end of the shaft 54 carries a lever 56 thereon. The lever 56 has a handle 51 including a spring-catch mechanism 58. The mechanism 58 is arranged to engage a suitable opening 59 in the left-hand standard 55. The purpose of this arrangement is that by turning the lever 56, the offset portion 53 is angularly moved, thereby bringing a greater or less tension on the straps 48. By this means, the straps 48 may be loosenedpto the point that they do not interfere with ready rotation of the drum when the hose is being either reeled in or reeled out, but at the same time the straps 48 may be tightened in such a manner that they constitute brakes against rotation of the drum.- In addition to acting as brakes against the rotation of the drum, the straps 48 retain the drum and its assembly on the rollers 9. That this arrangement is particularly effective will be seen when it is considered that the principal use of the present invention is on the rear platform of automobile tank trucks, which are frequently obliged to go over rough roads with considerable jolting. retaining strap 48, it might frequently be possible for the side plates I3 and I4 to jump off the rollers 9, and thereby cause trouble in the operation of the reel.

As has been indicated, the tension in the straps 48 Amay also be regulated in a semi-permanent manner by means of the slots 5U and bolts 5I. It has been found adequate for breaking and locking purposes, to have a total linear pull or displacement, occasioned by the offset portion 53, of about one inch, when the side plates I3 and I4 are of the order of three feet in diameter.

When the present invention is installed on an automobile tank truck. In the manner heretofore intimated. it may be made of such a dimension that it readily ts into the cabinet usually provided on the rear end of such trucks, without rebuilding the end platform of the truck. Under these conditions, it is customary for the crank 21 and the lever 56, together with the springpressed mechanism 58-59, to be located on the outer wall oi' the cabinet. This provides for ready availability of the device to the driver of the tank truck.

The present invention is ideally adapted for such installations inasmuch as it presents a reel, substantially the entire width of which is available for the storage of hose. In prior reels where the bearing system was such that the reel was borne on a central bearing as distinguished from the rollers 9 provided in the present invention, this efcient utilization of space was not possible inasmuch as the central bearings of necessity had to extend laterally beyond the confines of the reel itself.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As many changes could be made in carrying out the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawing shall Lacking the be interpreted as illustrative and not in a limiting sense.
